One of the mysteries of the English language finally explained.
The surgical opening or puncture of a vein in order to withdraw blood or introduce a fluid, or (historically) as part of the procedure of letting blood.
- ‘Blood was collected by phlebotomy from the antecubital vein.’
- ‘The student should be aware of one cause of pseudohyperkalemia, hemolysis, since it is not an uncommon occurrence when tourniquets are used during phlebotomy or when improper handing of a blood sample causes a breakdown of the cells.’
- ‘The performance of phlebotomy by nursing staff benefits the patient in that the blood specimen is collected and intravenous fluids are started at the same time, thus causing less trauma to the patient.’
- ‘Experimental reductions in cardiac index and hepatic blood flow induced by phlebotomy are rapidly corrected by albumin resuscitation, whereas crystalloids require double the volume.’
- ‘Patients may also undergo phlebotomy at a blood center.’
Late Middle English: via Old French from late Latin phlebotomia from Greek, from phleps, phleb- ‘vein’ + -tomia ‘cutting’.
